"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncomedi: Flush partial mappings in error case\n\nIf some remap_pfn_range() calls succeeded before one failed, we still have\nbuffer pages mapped into the userspace page tables when we drop the buffer\nreference with comedi_buf_map_put(bm). The userspace mappings are only\ncleaned up later in the mmap error path.\n\nFix it by explicitly flushing all mappings in our VMA on the error path.\n\nSee commit 79a61cc3fc04 (\"mm: avoid leaving partial pfn mappings around in\nerror case\")."

"value": "AV:L - The vulnerability is reached only via mmap(2) on a local comedi character device node (/dev/comediN); there is no network or physical-bus interface involved.\nAC:L - The attacker controls both sides of the condition — inducing the partial remap_pfn_range failure via memory pressure and racing a concurrent buffer free (BUFCONFIG/detach) — so per the UAF/attacker-controlled-race guidance this is Low.\nPR:L - Once a driver is attached (a common one-time privileged setup), an unprivileged local user with access to the device node can allocate a buffer and mmap it without any capability; the vulnerable comedi_mmap and buffer-resize paths have no CAP check.\nUI:N - The attacker performs the open, buffer allocation, and mmap entirely on their own; no victim action is required.\nS:U - The corruption stays within the kernel's own security authority (kernel-managed memory); no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The dangling userspace PTEs point at physical pages that are freed and reallocated to arbitrary kernel or other-process uses, giving the attacker a read primitive over reused memory.\nI:H - The stale mappings are writable (PAGE_SHARED), so userspace can write into freed/reallocated physical pages — an arbitrary write primitive suitable for privilege escalation.\nA:H - Dangling PTEs to reused physical pages readily corrupt kernel memory, causing oopses/panics and system instability."
